I saw that and it surprised me when the colors A and B are the same!

Ahhh I know, I saved it and opened it in paint, cut it and put them together, and punched a whole in the wall when I saw that it was the same... I still don't believe it.

I just checked it as well. Definitely pretty interesting. :)

It annoys the hell out of me that it's the same shade =P

WTF?

Eventhough I know it is the same, it still isn't the same! WTF!?

I dont know, maybe when you put light on the dark squares their shade turns light. When light is on the light squares, they turn dark. Then when light and dark are in the shade, they turn the opposite? So then B is really a dark square that is turning a light shade?

I think it also has something to do with the relative surrounding colors. If you stare at the upperright corner of square B, you'll notice out of the corner of your eye that the other light squares down it's diagonal (in the path of the shadow) begin to appear darker. :)

While I did notice it, it still didn't seem nearly as dark as square A.

Why is the solarized copy still called "original"?

I decided to try and recreate this illusion in a simpler form.

The shading of the white and black blocks surrounding the middle block is what confuses your eye.

In the original, it's a black and a white square that are the same color though...

Color contrast.. it's why when you watch a dark movie during the day you can't see shit :(

Yes. =)

By changing the pattern of shading, I created a similar illusion making it seem as if two white blocks were different colors.

That's not as confusing as a black & a white block being the same color though.
